概括
甲基 (MTX) 单一治疗有效改善类风湿性关节炎 (RA) 症状,显示出疾病活性显著降低. 然而,MTX往往无法诱导缓解,即使在早期治疗.
科学领域:
- 类风湿病学 类风湿病学
- 药理学 药理学是指药理学的学科.
- 生物统计学 生物统计学
背景情况:
- 类风湿性关节炎 (RA) 是一种慢性自身免疫性疾病,需要有效的疾病修饰治疗.
- 甲托雷克萨特 (MTX) 是 RA 的基石疗法,但其在不同患者群体的最佳使用和有效性需要进一步阐明.
- 了解影响MTX疗效的因素对于个性化治疗策略至关重要.
研究的目的:
- 使用基于模型的元分析 (MBMA) 系统评估甲状腺素 (MTX) 单疗法在改善类风湿性关节炎 (RA) 症状和功能方面的疗效.
- 调查治疗持续时间,剂量和患者基线特征 (疾病持续时间,CRP,ESR) 对MTX疗效的影响.
- 根据开发的疗效模型,预测12周的治疗结果.
主要方法:
- 69项随机对照试验 (RCT) 的系统综述和基于模型的元分析 (MBMA) 涉及7999名RA患者.
- 开发疾病活动评分28 (DAS28),美国风湿病学学院20% (ACR20) 和ACR50反应标准的疗效模型.
- 为了估计DAS28,ACR20和ACR50.0的最大疗效 (Emax) 和达到50%最大疗效 (ET50) 的时间,进行了模拟.
主要成果:
- MTX显示出显著的疗效,Emax对DAS28的减少为-54.90%,Emax对ACR20的反应为70.3%,ACR50的反应为49.4%.
- 达到50%的最大反应 (ET50) 的时间有所不同,ACR20是最快的 (6.69周),DAS28和ACR50需要更长的持续时间 (分别为20.6和27.3周).
- 无论是MTX剂量还是患者特异性因素,包括疾病持续时间,C-反应蛋白 (CRP) 或红细胞沉率 (ESR),都没有显著影响治疗疗效.
结论:
- 单独使用甲德治疗是有效的治疗类风湿性关节炎症状和改善功能,特别是在疾病的早期阶段.
- 尽管在降低疾病活性方面有效,但MTX单疗法在RA患者中经常无法实现完全缓解.
- 缺乏剂量或患者基线因素的影响表明MTX的有效性概况一致,但强调需要组合疗法或替代策略来实现缓解.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
98
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
97
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
84
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Genome-wide Association Studies-GWAS
12.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
